In the last months duplicate groups appeared and disappeared again on their own, so I didn‘t follow the issue too closely anymore. I can‘t remember seeing one since the last update, but OTOH I didn‘t have a lot of time for roon lately.
I will have a closer look in the coming days and give feedback again!
Thank you again for the update and sorry this one is still bugging the system for you. We’ll reinvestigate and try to ship any potential fix sooner than the first round, but I don’t have a specific timeline for the ticket yet.
